*Hello,*
*
*
* I have the following scenario. I am trying the filter out the
interconnect links from the LIB table and the LFIB table. The layout of the
network can be found at
**http://i28.tinypic.com/2gtndyh.jpg*<http://i28.tinypic.com/2gtndyh.jpg>
* So far Router 1 is the only device which is correctly filtering out the
interconnected links. I checked the configuration on the other routers and
they looked correct to me. Below is also the outputs that Router1 is
filtering the interconnect links. Also below is the output of BB1 that
showing that the other routers are not filtering correctly. Below is all the
MPLS and access list for configuration portion. *
*
*
*Thank you *
